GO:0032991
|
protein-containing complex
|
A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together. |
|
GO:0005575
|
cellular_component
|
A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology: (1) the cellular anatomical entity where a gene product carries out a molecular function (e.g., plasma membrane, cytoskeleton) or membrane-enclosed compartments (e.g., mitochondrion); (2) virion components, where viral proteins act, and (3) the stable macromolecular complexes of which gene product are parts (e.g., the clathrin complex). |
|
GO:0005622
|
intracellular anatomical structure
|
A component of a cell contained within (but not including) the plasma membrane. In eukaryotes it includes the nucleus and cytoplasm. |
|
GO:0110165
|
cellular anatomical structure
|
A part of a cellular organism consisting of a material entity with granularity above the level of a protein complex but below that of an anatomical system. Note that cellular organisms exclude viruses. |
|
GO:0043226
|
organelle
|
Organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, and prokaryotic structures such as anammoxosomes and pirellulosomes. Excludes the plasma membrane. |
|
GO:0043229
|
intracellular organelle
|
Organized structure of distinctive morphology and function, occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton. Excludes the plasma membrane. |
|
GO:0043228
|
membraneless organelle
|
Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane. Includes ribosomes, the cytoskeleton and chromosomes. |
|
GO:0043232
|
intracellular membraneless organelle
|
Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane and occurring within the cell. Includes ribosomes, the cytoskeleton and chromosomes. |
|
GO:0005694
|
chromosome
|
A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. |
|
GO:0099080
|
supramolecular complex
|
A cellular component that consists of an indeterminate number of proteins or macromolecular complexes, organized into a regular, higher-order structure such as a polymer, sheet, network or a fiber. |
|
GO:0000940
|
outer kinetochore
|
The region of a kinetochore most external to centromeric DNA; this outer region mediates kinetochore-microtubule interactions. |
|
GO:0000776
|
kinetochore
|
A multisubunit complex that is located at the centromeric region of DNA and provides an attachment point for the spindle microtubules. |
|
GO:0000775
|
chromosome, centromeric region
|
The region of a chromosome that includes the centromeric DNA and associated proteins. In monocentric chromosomes, this region corresponds to a single area of the chromosome, whereas in holocentric chromosomes, it is evenly distributed along the chromosome. |
|
GO:0000779
|
condensed chromosome, centromeric region
|
The region of a condensed chromosome that includes the centromere and associated proteins, including the kinetochore. In monocentric chromosomes, this region corresponds to a single area of the chromosome, whereas in holocentric chromosomes, it is evenly distributed along the chromosome. |
|
GO:0098687
|
chromosomal region
|
Any subdivision of a chromosome along its length. |
|
GO:0000793
|
condensed chromosome
|
A highly compacted molecule of DNA and associated proteins resulting in a cytologically distinct structure. |
|
GO:0031262
|
Ndc80 complex
|
An essential outer kinetochore complex involved in the attachment of microtubule ends to the chromosomes during mitosis. |
